Loving this dress. However the armpit/arm area is really tight. Do not recommend for people with large arms. For reference I’m 5ft4, curvy body type and about 150lbs. I got 2XL. I do however have larger arms than most people my size but I still think even for the general public, the armpit area is tight. The dress length lands right at my ankles. The dress is a bit stretchy and forgiving so I’m able to sit down with ease.
